Great comparison!
I love both players! When I was starting to play basketball MJ was the king, and Bulls was dominating NBA at their peak! The moves, the passes, slam dunks, or flying towards the basket.... all was magical when Michael Jordan was touching the ball!
On the other side LeBron, was the kid, who has great body shape, working really hard. When time went, he proved that the main trait for LJ is: he is a game changer! He is natural born leader, which communicates to excellent level on the court. Any team he joined went far in NBA playoffs, won way more games in regular season before him. Clevelend never won any major sport championship, before Lebron brought NBA trophy to Clevelend! This makes him and his personality special.

Like I said: I m a fan of both those players!
